Based on the oxidative stress theory, aging derives from the accumulation of oxidized proteins induced by reactive oxygen species (ROS) in the cytoplasm. Hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) elicits ROS that induces skin aging through oxidation of proteins, forming disulfide bridges with cysteine or methionine sulfhydryl groups. Decreased Ca<sup>2+</sup> signaling is observed in aged cells, probably secondary to the formation of disulfide bonds among Ca<sup>2+</sup> signaling-related p ...[more]
